DERRICK FOR PUMPING OIL-WELLS.

Specification of Letters Patent.

Patented Aug. '7, 1906.

To all whom it may concern:

Be it known that we, GURnoN EUGENE KEELER and SILAs WILLsON GENsoN,citizens of the United States, residing at Haskins, in the county ofWood and State of Ohio, have invented certain new and usefulImprovements in Combination- -Derricks for 1 Oil- Wells, of which thefollowing is a specification. a

This invention has relation to a combination-derrick for oil-wells,Artesian wells, and other deep wells, and has for itsobject theprovision of novel means for handling the sections of well-tubing whilethey are being inserted in or withdrawn from the well and while suchsections are being coupled or uncou led.

T is invention has for its further object the provision of novel meansfor holding the pumping-jack in position while the pumping operation isbeing proceeded with.

Our invention consists in the novel construction, arrangement, andcombination of parts hereinafter set forth.-

Referring to the accompanying drawings, illustratin our improvement, inthe figures of which li re numerals designate corresponding parts,Figure 1 is a perspective view of a derrick and its appurtenant partsconstructed according to our invention; and Fig. 2 is a fragmentaryview, artly in section, and on an enlarged scale, of the lower portionof the derrick. v

The main body of the derrick is composed of two uprights, (designated,respectively, 1 and 2,) such uprights being of wood or of steel, as maybe desired. The uprights 1 and 2 are so disposed as to form a framewhich tapers outward sli htly from the top to the bottom thereof. T euprights 1 and 2 have plates 12 12 bolted to their outer sides at theirlower ends, these plates penetrating the earth and serving to maintainthe lower end of the frame in fixed position. The frame is held rigid atits lower end by a cross-beam 13, which is secured in any suitablemannerto the uprights 1 2.

In placing the frame in position for operation it is inclined slightlyto one side, so that the upper end will be inclined toward the ointwhere the well is to be driven, and the ame is sustained in the requiredposition by guy ropes or cables 8 8, attached to the frame at 22 andwhich are provided with turnbuckles 9 9 and which are secured at theirlower ends to anchors 10 10, located below the surface of the earthadjacent to the derrick. Stay-braces 11 are attached to the up rights 12 at a pro er distance from the bottom of such uprig t, and thesestay-braces are secured to an anchor 14, located below the surface ofthe earth.

A sheave 15 is journaled between the upper ends of the uprights 1 2, anda cable 19 passes over this sheave and through two pulleyblocks 20 20,this cable 19 passing around a sheave located near the bottom of theframe and then extending rearwardly and carrying on its end a hook 24,by means of which it may be attached to a traction-cable in the usualmanner.-

An arm 21, which is indented on its upper edge, projects horizontallyfrom the upright 2 near the upper end thereof, the inner end of said armextending through said upri ht 2 and being held in position by nuts, ass own in Fig. 1. A brace-rod extends fromthe outer end of the arm 21 tothe upper end of the upright 1, and the upper pulley-block 20 issuspended from the arm 21 by means of a hook 27. The lower pulley-block20 carries a hook 23, which hooks into an eye on the upper end of apump-rod 7, which pump-rod is connected to the pump-jack 5 by means of alink 5, which is pivotally attached to the pump-rod 7 and ivotallyattached to the pump-jack 5, as 0 early illustrated in Fig. 2. The 'pum-jack 5 is journaled in angle-plates 17 18, b0 ted, respectively, to theinner sides of the uprights 1 2 and the braces 11, and

said pump-jack is of substantially triangular form and has projectingupwardly from one corner a segment-piece the outer surface of whichcorresponds to an are described from the pivotal point of the jack. Thelower corner of the jack carries triangularlates which are boltedtogether, so as to em race the side members of the jack and form atriangular frame, to which frame is pivotally attached a shackle-rod 25.V

A pump 6 is shown in Fig. 1 of the drawings, and in the condition ofparts shown in thls fi .ure the apparatus is adapted for pumping, w ichis effected by imparting a reciprocating movement to the shackle-rod 25.This reci rocating movement is imparted to the shaclile-rod by a pitman,which is shown at the leftehand end of the shacklerod in Fig. 1 of thedrawings, this p'itman receiving movement from the crank-shaft of anengine. (Not shown.) During the umping operation the cable 19 is allowedsufficient slack to permit of the rise and fall of the pump-rod 7 but iffor any reason it is desired to draw the pump-rod out of the Well thepump-rod is uncoupled from the .pum jack 5, and by exerting traction onthe cab e 19, which may be done by attaching the hook 24, carried by thecable 19, to a ro e which is Wound around a drum operated an engine orin any other suitable and "wellknown manner, the pum p-rod will bedrawnupwardly and out of the pump. The cable 19 -'and the pulleys 2O 20 arenot only utilized for drawing the pum -rod out of "the pump, but, aswill be readi y understood, may be utilized for raising, lowering, andotherwise handling the well-tubing and sustaining the sections of thesame as they are being coupled and uncoupled when placing them in thewell or takingout thesame.

We claim '1 The combination with an upright flame, a notched armprojecting horizontally from said frame near 1138 upper end, a hookengaging said notched arm, of a pulley-"block susended'from said hook, asecond pulleyblock disposed below the first-named pulleyb'loc'k, asheave located at the upper-end of the frame, a sheave located at thelower end of the frame and a cable passing over said sheaves andthroughsaid pulley-blocks.

a second 2. "The combination with-a frame composed of uprights attachedtogether at their u per and -lower ends, of an arm; rejecting om saidframe near its upper end? a ulley-block carried by said arm and adjustahle thereon,

u-lley-block disposed below the first-named ulley-block and a cableassing through sai pulley-blocks, of a pump aving a pump-rod connectedto said second pulleyblock and means for vertically moving the pump-rodindependently of the movement of said pulley-block, substantially as de:scribed. v

3. The com'bina'tion in a derrick for wells, of up'rights connected attheir upper and lower ends, andeonstituting a frame, a horizontally-extending 'notched arm carried by said frame near its upper end, a hookcarried by saidarm and adjustable thereon, a pulle-yblock carried bysaid hook, a second pulleyblock disposed below the fir t-namedpulleyblock, a hook carried by said second pulleyblock, a pui'np 'rodengaged by said hook, sheaves-carried'by said framepa cable passing oversaid sheaves and through said pulleyblocks, pumping appara'tusconnectedtosaid pump-rodand-means for o erating thepimipmg apparatus, substantia1y as described.
